.The instrument shown iintth'e drawing com- ,prises :a ecylindl fial tubular :member will wherein .is wreciprocable: a :rod or iston member 112;; both "of rthesex-mem ers preferabl being formed (of a r nsparent :plastic material such as fl-Incit Extending. rIongitudinally from the right-hand end of the tubular member, to a point spaced some distance from" the left-hand end thereof,

is a slot, the edges of which are indicated at l3.

Projecting through this slot is a pin M which is preferably rigidly secured to the rod 12 as by threading or pressing in a transverse hole therethrough. The pin is a free fit in the slot and is provided at its outer end with a hook l5.

.eral .use, and. so for holding .that diaphra in stretched condition .the ,pin |,4 is inserted .in .the

.one of .the notches .l6 nearest to .theleft-hand end of the instrument. When ..diaphragms .of

,larger size .are employed, a, notchzcorlresponding tc the particular size is selected' for .the pin.

, Before applying .the diaphra m to the .instrument, a quantity .of i-medicamentis. injected .into

.the,mouth 1, of the tubular member. This. medica- Jnent, indicated .at .is preferably. an antiseptic ,jelly .of the type tusually prescribed :ior .use with the diaphragm. -',I he, 1"ell ismarketedin flexible .metal rtubes having mecks .of a. size receivable .in

.In Figures 1 and 2, the instrument is shown in condition to hold a. diaphragm, indicated in broken lines at IT, which may be of the usual rubber type having a resilient bead IS. The diaphragm is stretched, as shown in Figures 1 and 2,

instrument is inserted to the proper position in the vaginalqcanah ,the ,right han'd end ,of .the

tubular, ,member serving as -a handle.

The particular tion, and that I intend therefore to be limited only by the scope of the appended claims.

I claim as my invention:

1. A gynecologic, instrument comprising an elongated tubular member, a piston member reciprocable in said tubular member, said tubular member being adapted to receive medicament and having an open end through which said medicament is ejected by movement of the piston member toward said end, and cooperating means on said members whereby a flexible diaphragm can be held in stretched condition for insertion in the vaginal canal and released from the members in the medicament-ejecting movement of the piston member.

2. A gynecologic instrument comprising an elongated tubular member open at both ends and forming a handle for the instrument, a piston member reciprocable in said tubular member and of a length greater than that of the tubular member, said tubular member being adapted to receive medicament in one end thereof when the piston member is partly withdrawn therefrom, and cooperating means on said members for holding a flexible diaphragm in stretched condition for insertion in the vaginal canal when the piston member is in said partly-withdrawn posi tion, said diaphragm-holding means being so arranged that the diaphragm is released from the members when the piston member is moved toward said one end of the tubular member to eject said medicament.

3. A gynecologic instrument comprising an elongated tubular member open at both ends and forming a handle for the instrument, a piston member reciprocable in said tubular member and of a length greater than that of the tubular member, said tubular member being adapted to receive medicament in one end thereof when the piston member is partly withdrawn therefrom, and a hook carried by said piston member for engaging the bead of a flexible diaphragm so that when the bead is stretched between the hook and said one end of the tubular member while the piston member is in said partly-withdrawn position the diaphragm can be inserted in the vaginal canal, said hook being so arranged that the bead is released therefrom when the piston member is moved toward said one end of the tubular member to eject said medicament.

, 4. A gynecologic instrument, as defined in claim 3, including means for maintaining said members in diaphragm-stretching condition while inserting the diaphragm, said means being operable to active or inactive condition by relative rotation of the members.

5. A gynecologic instrument comprising an elongated tubular member open at both ends and forming a handle for the instrument, a piston member reciprocable in said tubular member and of a length greater than that of the tubular member, said tubular member forming at one end a receptacle for medicament when the piston member is withdrawn from that end, a portion of the tubular member away from said receptacle being slotted longitudinally, and means projecting from the piston member through said slot and providing at its outer end a hook for engaging the bead of a flexible diaphragm, the mouth of said one end of the tubular member being formed to engage an opposite portion of the diaphragm bead so that when the piston member is in said withdrawn position the bead can be stretched between said hook and said mouth for insertion of the diaphragm in the vaginal canal and there released when the piston member is moved toward said one end of the tubular member to eject the medicament from said receptacle, said slot being of a length sufilcient to permit such relative movement of the members.

6. A gynecologic instrument, as defined in claim 5, wherein an edge of said longitudinal slot is provided with a notch for receiving the adjacent portion of said hook-providing means so that the tubular member can be maintained in its withdrawn position while inserting the dia phragm in the vaginal canal.

'7. A gynecologic instrument comprising an elongated tubular member open at both ends and forming a handle for the instrument, a piston member reciprocable in said tubular member and of a length greater than that of the tubular member, said tubular member forming at one end a receptacle for medicament when the piston member is "withdrawn from that end, said tubular member having a slot extending longitudinally from a point spaced from said receptacle-forming portion to the other of the ends of the tubular member, and means projecting from the piston member through said slot and providing at its outer end a hook for engaging the bead of a flexible diaphragm, the mouth of said one end of the tubular member being formed to engage an opposite portion of the diaphragm bead so that when the piston member is in said withdrawnposition the bead can be stretched between said hook and said mouth for insertion of the diaphragm in the vaginal canal and there released when the piston member is moved toward said one end of the tubular member to eject the medicament from said receptacle, an edge of said longitudinal slot being provided with a notch for receiving the adjacent portion of said hookproviding means so that the tubular member can be maintained in its withdrawn position while inserting the diaphragm in the vaginal canal.
